Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed December 6, 1911. Serial No. 664,229.

To all whom it may concern:

Be it known that I, \VALTER W. SMITH, a citizen of the State of Wisconsin. United States of America, residing at Gillett, \Visconsin, have invented. certain new and useful Improvements in Sectional Flanges, of which the following is a specification.

The invention relates to coopering, and more particularly to improvements in a clamping device or chuck for holding the staves of a bucket in proper relation, for

turning the outer surface of the bucket and thereby evening the surface thereof, prior to applying the hoops thereto.

An object of the invention is to provide an improved chuck from which the bucket may be easily taken, after the same has been turned and after a hoop, or hoops, have been applied. I

A further object of the invention is to provide a chuck of the character described which may be applied to and used in connection with either a vertical or a horizontal lathe of ordinary construction.

With these and other objects in View, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and claimed.

In describing the invention in detail, reference. will be had to the accompanying drawings forming part of this specification, wherein like characters designate corresponding parts in the several views, in which- Figure 1, is an elevation view of my proved chuck, having a number of staves clamped therein, in position for being turned; Fig. 2, is a horizontal section taken on the line 2--2of Fig.1; Fig. 3, is a vertical sectional view taken on the line 3-3 of Fig. 2; and Fig. 4,'is a fragmental vertical sectional detail, taken on the line 4 -4 of Fig. 2, and showing the manner of raising and lowering the segments.

Referring more particularly to Figs. 3 and 4, for the details, A is a spindle having a collar B shrunk thereon; its end C being screwthreaded. Rotatably seated upon the spindle, is a brim-engaging disk. or main disk, which will hereinafter be known as the rabbeted diSkyQJld this disk has a peripheral rabbet d therein. An eccentrically apertured disk E is concentric to the disk D and to the spindle A and is fixed to the disk D by means of stay-bolts F. A sleeve G is rotatably mounted on the spindle, and has at fixed to a special lathe. good service,

a Fig. 4; whereupon,

sized and are then one end a radial flange 9 containing apertures through which the stay-bolts F extend, and also having apertures g and having lugs g adjacentto the apertures 9 Links H are pivoted to said lugs at g". Each alternate link I-I being slotted at one end as at h for a purpose hereinafter explained.

The disk E has apertured lugs e thereon, and through the apertures thereof extend pivots e to which are connected the segmental plates I. Thes plates are rabbeted on their arcuate edges as shown at z. for a purpose hereinafter shown. The plates I have apertured lugs extend; and to each of these pivots is connected anend of a link H. Anut J is screw-threaded onto the portion C, of the spindle, and is connected to sleeve G by means of a' union coupling device as illustrated at R which operates sleeve G and consequently all parts connected therewith as the nut I is turned one way or the other. A collar K is fixed on the spindle A in proximity with the disk D. p

In Fig. 1, the chuck is repres nted as having staves L secured in position for the turning operation, and it may be noted that, with-this object in view, the outer surfaces of the staves', extend beyond the peripheries, respectively, of the main disk and the plates I. The disk I) is. provided with a hub M which is designed to have frictional contact with.the collar Br In operation, thechuck is permanently For best and ongv it must be so arranged that there be no obstruction adjacent to, the threaded portion C so that after the bucket has been turned, the plates may be caused to assume the position shown in dotted lines, the bucket may be moved in its axial direction and removed from the chuck over the nut J and the threaded portion C. I have indicatedv only a sufficient portion of the actuating mechanism as will sufiice to show the connection of my improved chuck therewith, and this actuating mechanism comprises a band wheel N, secured on the shaft A, and adapted to be connected, by friction -bel't transmission, with any proper source of power. The shaft A is journaled in bearings O, and is provided witha thrust-preventing collar P, the

sleeve B also preventing thrust motion 0 the shaft. In applying thestaves to the chuck they are, of course, first properly fitted within the rabbets 5 through which pivots i connection with flange I, thus compelling drawing disk 9 in the same direction and operating links ll which force the sections oi flange 1 into position as shown in dotted lines in Fig. l. "When inclosed position, the sections of flange I fit closely together at their sectional edges, forming one complete and solid flange. Each alternate link rl slotted at the opposite end from its the unslotted links to move its section of the flange out of the way of its neighbors before the other begins to move. The pail, bucket or tub, being turned, is then removed over the nut J, and another is inserted and clamped into position, and the motion of the nut is reversed to firmly clamp the work into position. After being chucked, the spindle is rotated, thereby rotating the bucket which may have its exterior surface evened by the use of any proper tools or u'ieans. After the surface of the bucket has been properly evened, hoops may be applied in the usual way and the bucket removed in the manner described in the foregoing. It is obvious that in order to raise the plates into the dotted line position shown in Fig. i, certain of the plates must be raised before other of the plates rise, in order that their radial edges shall not condiet, and to provide for this condition, the pivots 57*, in certain of the lugs g are slidable in the slots h, and it is obvious that while the non-slotted links are being moved, the slotted links will remain at rest until the plates 1, which are connected to the non-slotted links, have been moved stillicient-ly to allow the alternate plates to be moved without interfering therewith. The

plates connected with the slotted links are not moved until the pivots 9 have traveled length of the slots 72, and contact the end thereof.

lhe invention is obviously susceptible of numerous modifications of construction without departure from the spirit and scope of the invention as shown and hereinafter claimed, and is not confined to the manufacture of buckets; being obviously applicable in the manufacture of tubs, kegs, barrels, hogsheads and the like.

I claim;
